Someone told me that milk in NZ is more expensive than petrol. I hadn't thought of it but when I went to my local dairy, the milk was $4.49 for a 2 litre. That's about more than petrol! There is a good article on it here.
It's not the case everywhere, you can find it on special at times for $3.50. Still, even at that price, it does seem highly inflated... Especially since most 2 litre soft drinks can be purchased well under $3.00.
Is there any reason why a nation that produces so much milk charge so much for it? It can't possibly cost more than the processing, importing and taxing of petrol! Can it?
